on an Ubuntu 10.04 system, bootstrapping portage fails with:
make: Entering directory
/cache/ttt/prefix-20111201/local/bin/install -c -d -m 755 -o "luebeck"
-g "ldfm" /cache/ttt/prefix-20111201/local/usr/lib/portage/bin
/cache/ttt/prefix-20111201/local/bin/install: cannot change owner and
permissions of `/cache/ttt/prefix-20111201/local/usr/lib/portage/bin':
Operation not permitted
The file system is tmpfs. ldfm is the default group of the user. On
this system, setting the owner and group of a file which is already
owned by that user also fails, both with the chown executable that
Ubuntu installs and the one installed after bootstrapping coreutils.
Has anyone seen this before? Any ideas what might cause this?
